To all whom t may concern.

Be it known that l, Cin-muis MATnJoWrTz, a citizen of the United States, and resident of Kenosha, in the county of Kenosha and State of lVisconsin, have invented new and useful Improvements in TWeed-Exterminators, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specix'ication.`

This invention relates to improvements in weed eXterminators and more particularly to that type adapted to dest-roy quack grass. It is one of the objects of this invention to pro-vide a Weed exterminator Which is adapted to dig into the ground and engage the roots of quack grass and pull the said grass out of the ground and deposit it upon a tiltable platform.

A further object of the invention is to provide a Weed eXterminator having a rotary digging means for engaging and pulling quack grass or other` Weeds from the ground.4

' as a general cultivator.

With the abovev and other objects in view the invention consists of the improved Weed exterminatorand its parts and combinations as set forth in t-he claims, and all equivalents thereof.

In the accompanying drawings in which the same reference characters indicate the same parts in all of the views: Figure 1 is a side-view of the complete Weed exterminator; Fig. 2 is a rear View thereof, parts broken away and other parts being shown in section; Fig. 3 is a sectional detail vieW thevvheels upon Which the frame is mounted.. This frame 1s ofrectangular form'and p a l said drums are rotated their teeth will pass provided with depending eared brackets 10 to which an angular tiltable frame 11 is pivotally connected. A shaft l2, extending transversely across the machine and through the eared brackets and the end port-ions of the tiltable frame, is journaled in said brackets yand is provided with .sprocket Wheels 13 on its outer ends. The transverse shaft l2 has also mounted medially thereon a small ksprocket Wheel lil which. is driven from the axle l5 hy the sprocket Wheel 16 and the sprocket chain 17'.' |The sprocket Wheel 1G is loosely mounted Aon theaXle l5 and is formed with clutch teeth 18 on one side of'its huh, and a complementary clutch member i9 splined to the axle is adapted to be moved into clutching engagement with the toothed hub hy means of the clutch lever 20 to cause the rotation of the shaft`l2. 'The tiltahle frame ,il is formed of tWo side members 2 depending from the eared brackets and having their rear ends con= nected together by the transverse angle bar 22 which is fastened to the extension 230i the side members 2l.

A digging drum 24 provided With radially extending teeth 'or pins 25 extends transversely across the space between the side members 2l, and the shaft 26 of said drum passes beneath said side members and is journaled in the depending boxes 27 fastened to the sides thereof. This drum is adapted to ride on the ground and engage the roots of quack grass or other Weeds as the vehicle travels over the ground. The drum is positively rotated at a faster rate of speed than the travel of the machine by sprocket wheel and chain connection 28 and 29, respectively, with thesprocket wheels- 13. A kicker drum 30 also provided with radially extending teeth or pins is journaled on the rear ends of the side members 2l and theteeth of said drum are adapted to clear the quack grass or other Weeds pulled by the drum teeth. 25 and kick it upon 'a platform 32 supported from the frame. The kicker drum is driven by a sprocket chain and wheel connection 33 with the drum shaft 26, and is arranged to rotate at a fasterrate of speed than sain shaft. In order to completely clear the teeth of said drums from the material gathered a toothed plate 3ft extending across the' lower portion of ther tiltable frame is positioned in the paths of movement ot the toothed cruin and the 'kicker drum so that when sol through the inter-tooth spaces of the plate and strip the material therefrom. The teeth of one of the drums are staggered with relation to the teeth of the other drum and the teeth of each drum pass through alter- -nate inter-tooth spaces of the toothed plate in order to freely pass by each other. As the teeth of one drum overlap the teeth of the other drum, and both drums rotate in the sanledirection, the material carried on the teeth of the drum 9.4 will he kicked o of said teeth by the teeth of the kicker drum 30 and deposited upon the platform 32, and the teeth of the kicker drum in passing at an angle through the vinter-tooth spaces of the plate, will be disengaged from the material 'which might be lflcarried thereby.

The platform 32 isy supported at its front end from the depending arms 35 of the tiltable frame and at its rear end is connected to the lower ends of links 36. The upper ends of these links are pivotally connected to the rear portion of the frame 8. These platform connections are all pivotally connected to the other parts to provide for tilting the platform when it is loaded with material. The rear end of the platform is curved upwardly to prevent the material. from falling ott' when the platform is in untilted position.

The rear end portion of the t'iltable frame is supported by rods 37, the upper ends of which extend through blocks 3S carried by' lever arms 39. These lever arms are mount ed on opposite end portions of a transverse rock shaft 40 which is journaled in the frame 8. .An operating lever il provided with a spring actuated dog 42 is fastened medially to the rock shaft 40 and is held in adjusted position by engaging the notched segment 43. The rods 37 extend loosely through the blocks 38 and are provided with nuts 44 on their upper ends. Coiled springs 45 surrounding the rods and interposed hetween the blocks 38 and collars /lt are adapted to hold the tiltable frame yieldingly in its lowermost position.

A seat 47 mounted on the frame 8 is provided for the operator and the levers are positioned conveniently with relation thereto.

In operation the machine is pulled over the ground by horses in the ordinary manner, and in moving forward the ch'ain connection between vthe wheels and the drums will cause the rotation of said drums, and the teeth of the lower drum to enter the ground and engage the roots of the quack grass or other like growth and pull the same upwardly and deposit the material on,

the platform before the teeth pass through the toothed plate. As the material is lifted out of the ground it will loe engaged by the teeth of the kicker drum and kicked olf of the first mentioned teeth onto the plat-form.

noemen The teeth of the drums in passing through the toothed plate will be cleared of anymaterial which` may cling thereto. When the platform is lled with the material the operatorpulls upwardly on the operating leverand lifts the lower nd ofthe tiltahle frame upwardly, and tlus movement raises the forward end of the platform and tilts. the material off lthe rear end thereof; Thev tiltable frame is also adapted tobe raised in the same manner. when itis desired to pass over ground without digging into the ground. i

From the seen that the Weed exterminator is of very movable frame, al digging drum mounted on the frame and vhaving a vertical movement withrelation thereto, said drum proforegoing description'it' will he .y
